tsudoku

Description

tsudoku (both short for "terminal sudoku" and inspired phonetically by other Japanese words such as "tsunami") is a user-friendly implementation of the classic game of sudoku that you can play in your terminal.

Supported/Tested systems

The below operating systems have been tested for working condition. Other Unix-based OSs are also likely to also be supported without much hindrance. The new Rust version should also work in Windows thanks to the use of the pancurses library, although you will likely need a Curses library compatible with Windows (e.g. pdcurses).

• Debian Linux
• Rocky Linux
• openSUSE Tumbleweed
• FreeBSD
• WSL (Windows Subsystem for Linux)
• Manjaro

Note for MacOS users: It's possible that this README will be marked as executable if you clone this repo directly and prevent you from easily viewing the file in a text editor. Alternative ways to view the files marked this way include the Unix command line utility less or terminal-based text editors such as vim/view or nano. The easiest and simplest to use is less. Examples are below:

$ less README.md
$ view README.md
$ nano -v README.md

Note for inexperienced WSL users: tsudoku will not be compilable or playable unless a WSL shell is opened first. A WSL shell should be easily accessible from either a PowerShell or Windows Command Prompt by running wsl.exe at the current terminal prompt. Also see the example below. If you are unsure how to install or setup WSL, please reference Microsoft's instructions. It's recommended to install on Debian Bullseye or newer.

• Ex: Running tsudoku from Windows Command Prompt or PowerShell.

> wsl.exe ~/.cargo/bin/tsudoku

This can also be found in tsudoku.bat on the main branch, which is also provided for Windows/WSL users. Double-clicking on this batch file should open up a Windows Terminal and automatically start tsudoku. Note that quitting tsudoku will also automatically close the instance/tab in Windows Terminal.

Note for PowerShell users: An alternative method to get a shortcut to tsudoku is to add the following function to your PowerShell profile. This file can be found by running > $env:USERPROFILE at a PowerShell prompt. This will allow you to run tsudoku directly from PowerShell in one step. Note that you will have to start a new instance of PowerShell after adding this to your PowerShell profile.

function tsudoku { wsl.exe ~/.cargo/bin/tsudoku }

Prerequisites

• The Rust compiler: rustc
• The Rust package manager: cargo
• A C compiler: gcc or clang
• A C-based TUI library: ncurses
• curl

Installation

From GitHub (recommended)

See the README at the main branch.

From Crates.io

Prerequisites Installation

NOTE: The following example assumes Debian or a Debian-based OS using the APT package manager.

$ sudo apt install build-essential libncurses-dev curl

- For rustc and cargo, follow the instructions at the official Rust website. The standard installation will work just fine for installing tsudoku. Follow the instructions after installing for sourcing cargo in the current terminal shell (closing out of the terminal and starting a new instance should also work).

NOTE: Source your shell's RC file to allow running tsudoku in the current shell instance.

• Examples:

$ source ~/.bashrc # if using bash
$ source ~/.zshrc # if using zsh

Install via Cargo

$ cargo install tsudoku

Usage

With in-game menu enabled:

$ tsudoku

With in-game menu disabled:

$ tsudoku -n
or
$ tsudoku --no-in-game-menu

Display usage information:

$ tsudoku --help

Remove all saved games

$ tsudoku -d
or
$ tsudoku --delete-saved-games

Updates

From GitHub

See the README at the main branch.

From Crates.io

Run the following sequence of commands to update tsudoku manually

$ cargo uninstall tsudoku && cargo install tsudoku

Uninstallation

From GitHub

See the README at the main branch.

From Crates.io

Run the following sequence of commands to completely uninstall tsudoku

$ rm -rf ~/.tsudoku $ cargo uninstall tsudoku

Status Update: 31 October 2024

Current release version: 2.2.8

Good news! The Rust port of tsudoku is now complete, fully playable, and ready for an official v2.0.0 release! This means that the original C++ version will no longer be maintained, and as the porting process revealed it was a bit of a buggy mess anyway. Anyone is welcome to notify me of a bug fix by email. If you have played tsudoku and enjoyed your experience, please let me know via email as well; I'd love to hear about it! Have fun playing!

What happened to v1.x?

If you're wondering what happened to v1.x, that is the original C++ version. Since all that work wasn't tracked in Crates.io, it will look like v1.x is missing; however, anyone who wants to see the v1.x source code can still find it on this project's Github page.
